You get  couplings that take up misalignment, like Oldham  couplings.



Trouble with those is, they do not "fasten" the "motor-end" of the  screw.  I 
simply machined hollow hubs with "interference-fit" bores for  screw-end and 
motor-shaft, oh, but NOT "set-screws", but CLAMP type fit.   Required a bit 
more care in machining, but result is the screw is axial with the  motor and is 
rigid, depending on motor's bearings for thrust AND radial  bearing.
